Application led July 30, 1917. Serial No. 183,610.

T0 all 'ui/tom it may conce/1in.:

Be it known that I, @HARLEY C. Inns, a citizen of the United States ofAmerica, residing at Enterprise, in the county of l-locking and State ofOhio, have invented certain useful improvements in Insulator-Erackets,of which the following is a specification, reference being had thereinto the accompanying drawing.

The present invention has reference generally to improvements in thatclass of insigned so as to be removably yet rigidly at-v tached to across arm by the employment of' a single fastening device.

More particularly this invention embraces the provision of anl insulatorbracketwherein the construction permits of the removable clamping of theinsulator wire engaging sections in position about a conducting wire.

Among the other aims and obj ects of this.

invention may be recited the provision of a device of the characterdescribed with a view to compactness, and in which the number of partsare few, the construction simple, the cost of production low and theefficiency high.

Other improvements and novel details in the construction and arrangementof the various parts of the apparatus will be ybrought out more indetail in the description to follow, which for a clear understanding ofthe invention should be considered in connection with the accompanying.drawings forming a part hereof, and wherein is disclosed for the purposeof illustration a convenient and satisfactory embodiment of theinvention. It is to be noted in this connection that minor changes inthe construction and arrangement of parts maj7 be made without departingfrom the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings inwhich Figure 1 is a side elevation of the invention partly in section;

Fig. 2 is a front elevation thereof;

Fig. 3 is a transverse section taken on line k3--3 of Fig. 1. j Similarcharacters of reference are employed in all the above described views toindicate corresponding parts. Referring now, more particularly, to theaccompanying drawings, there is provided a relatively straightsupporting arm 1 provided adjacent one end with spaced openings whichforni a pivot 2 about which is pivotally engaged a loop 3 formed on theouter end of the horizontal portion et of an angle 5. The verticalportion 6 is provided adjacent its opposite end with an opening 7 andlikewise the arm 1 is provided adj acent `its outer end with a screwopening 8 for receiving a bolt 9 the other end of which is also passedthrough the opening 7 until the `head strikes the outer surface of thearm 1.

"LA suitable adjusting element such as a nut 1() is adjustably engagedon the projecting Tthreaded extremity of bolt 9 and serves as a neansfor clamping the arms 1 and 5 to a cross arin 11 thus holding the armsin sub- .stantially rigid yet removable position on "lthe arm 11.

7With a view toward providing an im- Aproved insulator support anarcuate insulator receiving member 12 is connected at a pointintermediate its ends to the outer end of each arin 1 and 5 as indicatedin the drawings. IThis arcuate or semi-circular' member terminates atone end in a lip 13 having a slot 14C therein for a purpose to bepresently apparent. rlhe opposite end of each member 12 terminates in aloop 15 which is pivotally engaged in an opening 16 formed in one end ofthe removable arcuate or semi-circular insulator receiving member 17. Alip 18 is formed on the outer end of each removable member 17 forabutting lengagement with the adjacent lip 13 and each lip 18 isbifurcated and designed to form spaced ears 19 through which is arrangeda pintle 20 for pivotally supporting and clamping the catch 21. Each ofthese clamping catches consists of a body 22 which serves as a fingerpiece one end thereof being reduced forming opposed shoulders 23 whichlie upon opposite sides of the shank 24 the inner end of whichterminates in an ear 25 pivotally engaged on one of the pintles 20. Ofcourse subsequent to the swinging. of the removable member 17 to arrangethe lips 13 and 18 in abutting engagement, each catch is swung about itspivot so that the shank 2li will pass through the adjacent slot le' toallow the shoulders 23 to engage beneath the adjacent lip as indicatedin the drawings so as to latch the receiving members in closed positionso that they are arranged in a substantially circular torni. lhepreferred insulator means used in conjunction with the insulatorreceiving members in the present instance consist or two substantiallysemiglobular sections formed desirably of glass or other insulating'material 26 haif'ing grooied surfaces 27 and flat faces 28. The flatfaces are provided with transverse grooves 29 which register -with eachother to form an opening when the flat `faces are arranged in abuttingrelation with each other for accommodating a conducting wire 30 in themanner indicated in the drawing. The outer grooved faces are providedwith peripheral grooves 31 also adapted to register with each other andto be engaged by the receiving members l2 and l? in the manner indicatedthe drawings. T he bottoms oi the peripheral. grooves 3l are :formedwith spaced recesses 32 which are engaged. by studs 33 formed on theadjacent inner faces o t the receivinei members l2 and 17.

En use the horizontal por ion llot the angle arm 5 is disposed on across arm in the manner indicated while the arm l is disposed oppositeto the vertical portion G. The bolt is now engaged in the arms while thenut is applied to clamp the arms in a substantially rigid position.Subsequent to the arranging oi' the sections 26 about a wire they areplaced so that the studs on each stationarj7 receiving member l2 engagethe recesses in the adjacent section whereupon the removable receivingor clamping member is swung to engage the groove and also allow thestuds to engage the adjacent recesses, and subsequent to the arrangementof the lips in abutting relation with each other the clamping catch isswung downwardly to removably clamp the sections in a substantiallyrigid position.

As many changes could be made in the above construction and manyapparently widely different en'ibodiments of this invention could bemade without departing` from the scope thereof, and it is intended thatall matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative and not in alimited sense. It is also to ber understood that the language used inthe ollowing claim is intended to cover all the generic and specificfeatures of the invention herein described and all statements of thescope of the invention which, as a matter of language might be said totall therebetween.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent is An insulator bracket comprising a straightarm formed at a substantially intermediate point with spaced openingsand adjacent one end with an opening, an angle arm having a loop:t'oi'medat one end, said loop surrounding the stock between the spacedopenings thereby providingl a pivotal connection between the straightarm and the angle arm, and a bolt passed through the opening adjacentthe end or the straight arm and passing also through an opening in theangle arm, wherebythe bracket may be engaged on a cross arm, the anglearm and straight arm surrounding three sides of the cross arm and thebolt spanning the fourth side of said cross arm.

In testimony whereof l affix my signature.

@HARLEY C. ILES.
